Correct answer: D
Answer: First-come-first-serve (FCFS) Reason: FCFS is non-preemptive. The scheduler does not forcibly remove a running process; a process runs until it completes or blocks. No context switches due to preemption: because FCFS is non-preemptive, the OS does not interrupt a running process to switch to another.
